Application filed February 7, 1916;

To all whom it may concern:

Be it known that I, ALBERT J. LAMARRE, a citizen of the United States, residing at Pawtucket, in the county of Providence and State of Rhode Island, have invented new and useful Improvements in Track-Gages, of which the following is a specification.

This invention relates to certain novel and useful improvements in track gages and has particular application to an automatic track gage.

In carrying out the present invention, it is my purpose to provide an automatic track gage which will form an essential part of the hand car or other testing car or truck and whereby the gage or spread of the track rails will be indicated automatically so that the crew of the car may repair the trackway whenever necessary.

IVith the above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter set forth in and falling within the scope of the claims.

In the accompanying drawings, Figure 1 is a view in end elevation of a hand car equipped with an automatic track gage constructed in accordance with the present invention. Fig. 2 is a cross sectional view through the same. Fig. 3 is a fragmentary bottom plan view of the car and gage. Fig. 1 is an enlarged longitudinal sectional view through the axle removed from the car. Fig. 5 is a transverse sectional view through said axle.

Referring now to the drawings in detail, 1 designates a hand car of any suitable or preferred construction except as hereinafter described.

In accordance with my invention, I form one of the axles of the hand car of a tubular section 2 extending across the platform of the car and a solid section 3 mounted in one end portion of the tubular section 2 and rotatably mounted upon one end of the tubular section is one of the wheels of the hand car, while rotatably mountedupon the outer end of the solid section 3 1s a corresponding wheel of the car. Passed through the inner end of the solid section 3 of the axle is a transverse pin 4 and the ends of the pin 4 project through elongated slots 5 formed in the tubular section 2 at diametrically opposite points. Surrounding the outer tubular section 2 of the axle and fixed thereto and spaced apart from the ring 6 isa ring 7 and Specification of Letters Patent.

Serial No. 76,688.

interposed between the rings 6 and 7 is a coiled expansion spring 8 acting upon the ring 6 to force the latter and the axle section 3 outwardly. Arranged upon the platform of the hand car is a gage 9 including a dial 10 suitably graduated and a pointer 11 movable over the dial. The pointer 11 is pivoted between its ends for swinging movement and one end thereof is connected through the medium of a link 12 with the collar 6.

Normally, the finger 11 registers with a mark on the dial indicative of the normal track gage and as long as the rails of the trackway traversed by the hand car are properly spread apart the finger will remain in such position. WVhen, however, the rails are spread, the spring 8 forces the axle section 3 outwardly so that the car wheels may follow the rails and in this outward movement of the section 3 the finger 11 is swung under the action of the link 12 to indicate on the dial the degree of spreading.

In order to hold the movable section of the axle against movement under the action of the spring 8 so that the hand car may be used for purposes other than testing the gage of the rails, suitable mechanism is provided. In the present instance, this mechanism comprises a lever 12 pivoted between its ends Within a slot 13 formed in the platform of the car above the axle and the lower end of the lever 12 is pivotally connected to the ring 6 as at 14. This lever works over a segment 15 and is equipped with a locking dog 16. By means of the lever 12 the section 3 of the axle may be moved in either direction to bring the finger 11 into registration with the gage mark on the dial indicative of the proper gage of the track rails and the dog 16 engaged with the segment 15 to hold the parts against movement. The hand piece of the locking dog 16 of the lever 12 may be held against the adjacent edge of the lever by means of a clip 12 as clearly illustrated in Figs. 1 and 2 of the drawings, so that the locking dog may be held out of engagement with the guide, thereby permitting the apparatus to operate automatically.

While I have herein shown and described one preferred form of my invention by way of illustration, I wish it to be understood that I do not limit or confine myself to the precise details of construction herein described and delineated, as modification and variation may be made within the scope of the claims and Without departing "from the spirit of the invention.

I claim: 7

1. In an automatic track gage, a car, one of the axles of said car being formed of a stationary section and a movable section carrying Wheels respectively adapted to traverse the track rails, means for shifting the movable section when the Wheels traverse spread portions of the railsfa gage-connected to said movable section, and a lever and locking means therefor for holding said movable section against movement under the action of said means.

2.111 an automatic track gage, a car, one of the axles of said car being formed of a stationary section and a movable section carrying Wheels respectively adapted to traverse the track rails, means for shifting the movable section When the Wheels traverse the spread portions of the rails, a gage connected to said movable section, and means for holding said movable section against in vement under the action of said first means.

In testimony whereof I aflix my signature in presence of two Witnesses.

ALBERT J. LAMARRE.
